Shingle-machine



SAML. M. KING, OF LANCASTER, PENNSYLVANIA.

SHINGLE-MACHINE.

To all 'who/m, t may concern Be it known that I, SAMUEL M. KING, of Lancaster city, State of Pennsylvania, have invented new and useful improvements in stave and shingle cutting machines, which I call the box shingle and stave cutting machine with movable bottoms, and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

A, the frame; B, the upright posts into which the cog-gearing is inserted and supported; C, the upper cogwheel or driving wheel attached to a shaft and crank D. This cogwheel gears into a lower and larger cogwheel E having a crank F at each end of shaft, operating on each outer side of posts B. From the cranks F connecting rods G extend to and are attached to the sliding lids H, which gives them an alternate motion. These sliding lids H are of cast iron, and have steel knives I in front, and they operate on incline plane boxes J. IThe boxes J are of cast iron and rest upon and are fastened firmly to the frame A.

In the inside of boxes J I have four or more screws K which support cast viron plates, or adjustable bottoms L so that by raising or lowering the screws at any time, the iron plates or adjustable bottoms L are raised or lowered, and the boxes J are deepened or made shallow according to the thickness that the Staves or shingles are required to be cut and tapered.

The operator places the bolt or wood in one of the boxes J, and the lid H with its knife in front is moved forward and the edge of the knife works on the face of the box J and cuts the wood tapering, so that the box J contains the shingle or stave with its upper side planed smooth. The shingle then faces down behind the box J, and is picked up by the operator and placed in the opposite box J, and by the lid of the box moving forward, the shingle is linished and passed out underneath.

The great advantage of this machine is its remarkable simplicity, and cheapness-and likewise the wood is not required to be steamed, but is cut lengthwise with the grain smoothly, without shattering the stave in the least.

Vhat I claim as my invention and desire to secure by Letters Patent is- The combination of cast iron boxes with adjustable bottoms and sliding lids operating with the knives in front alternately by connecting rods, so as to cut and regulate the size and taper of the shingle substantially as
